Using a mandoline, slice the potatoes into fries. I don't worry too much about the size of fry I am making- some are bigger, and some are smaller. That's fine!

Next, place your spuds in a nice cool water bath. Completely submerge the fries in water.

Let fries sit one hour. This helps to remove excess starch and will help the fries crisp up more in the oven.

After an hour, drain the water, and pat fries dry with a paper towel.

Toss with a couple tablespoons of olive oil, salt and pepper.

Spread out onto a baking sheet which has been generously sprayed with cooking spray (two if the sheet is too crowded- fries should not be super packed on the sheet).

Bake at 400 for about 30 minutes- until fries start to get soft.

You might want to stir the fries at this point to prevent excessive sticking and to flip the fries to the other side.

Turn the oven to 450 and continue baking until crisp (about 20-30 minutes).

If you get in a hurry, turn on the broiler to crisp up the fries- but watch them closely, and stir them a few times to be sure all sides get some good crunch!
